JOI-IN WALDHEIM, 0E NEWARK,.NEW JERSEY, ASSIGNOR, BY MESNE ASSIGNMENTS,

TO UNION TYPEWRITER COMPANY, OE JERSEY CITY, NEW JERSEY, A CORPORA- TION0E NEW JERSEY.

To all fr0/wm tm/ay concern Be it known that I, JOI-IN W'ALDHEIM.citizen of the United States. and resident of Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Type-Vrit-ing Machines, of which the following is aspecication.

My invention relates to typewriting machines and more particularly totabulating mechanism.

The main objects of my invention, generally stated, are to providecomparatively simple and eflicient tabulating mechanism by which anydesired columnar position may be selected at will, and by which anydesired denominationalc position in a column may be 4selected, so thatthe carriage may, after a single run, be arrested at any desiredcolumnar field or at any desired denominational posit-ion within anyselected columnar field.

A further Aobject of my invention, genen' ally stated, is to providecomparatively simple and efficient means whereby certain parts of thetabulating mechanism may be.

locked in the position to which the said part'or parts may be set ormoved under key control, and to automatically release the locking meansduring a subsequent operation of the tabulating mechanism.

A still further object of my invention is to provide tabulatingmechanism for arresting the carriage at variable posit-ions in 4thetravel thereof, the variable position of arrest of the carriagedepending on a variable movement of a fulcrumed member, and a variationof the fulcrum of said member bringing about a variation in the movementwhich may be given to said member.

'w-w of Fig. V3 and looking in the direction of the arrows at said line.Fig. 2 is a detail perspective view of a group of two of the keyactuated levers, together with certain of the associated parts foractuating the denominational stops. Fig'. v3 is a. fragmentaryhorizontal sectional view of the machine, the section being taken on theline wof Fig. l and looking in the direction of the arrows at said line.Fig. 4 is a fragmentary detail sectional view of the denominational stoplevers and certain of the associated parts, the section being taken onthe line g/-y of Fig. l and looking in the direction of the arrow atsaid line. Fig. 5 is a diagrammatic side elevation, partly in section,of the tabulating mechanism, the view illustrating the parts in theVshown only so much of a typewriting mac chine as may be necessary toarrive at an understanding of my invention.

I have shown my invention embodied in the present instance in a No. l5Yost machine, except in so far as the tabulating mechanism of thatmachine may be modified ror replaced by features of the presentinvention and except in so far as that machine may be modified to eectan embodiment of my present invention therein. Moreover, some of theparts of the typewriting machine are conventionally repre sented inorder to simplify the showing. It should'beV understood, however, thatthe invention may be embodied in various styles of typewriting machinesand that various changes may be made in the construction toV facilitatesuch embodiment.

The present case is one of three companion applications filed by me ofeven date herewith, the other applications bearing Serial Nos. 663,982and 663,983 respectively. Considered from certain broader aspects thereare features in common in all three cases. The broader claims tofeatures common to all three applications are included in case SerialNo. 663,982, whereas any feature common alone to caseSerial No. 663,983and the present application are broadly claimed in case Serial No.(363,983, theclaims herein beingrestricted to features not disclosed ineither ot' the other companion applications.

The frame of the machine comprises side plates l united by a rear crossplate 2 and top plates 3 and 4t. A carriage 5 is mounted to travel fromside to side of the machine on anti-friction balls or rollers 6; acylindrical platen 7 being carried by the carriage. The carriage ismoved in the letter feed direction under the power applied thereto bythe usual spring drum 8. The usual or any suitable cscapement mechanismis employed to control the carriage in its step-by-step letter feedmovement, only so much of the escapement mechanism being shown as may beof value in the consideration of the present invention. Thus ahorizontally disposed feed rack 9 is provided with upwardly extendingarms 10 pivoted at 11 to depending lugsv 12 on the bottom of thecarriage. A spring 13 tends to force the feed rack forwardly intoengagement with a feed pinion 14. which isoperatively connected to theusual escapement devices. A cross bar 15 is fixedly connected to theframe of the machine, and constitutes a support for a bracket 16, iixcdto the cross bar by screws 17. A releasing device or lever 1S is pivotedon a shouldered pivot screw 19, carried by the bracket 16. An engagingface or shoe 2O is provided on the release lever for contact with thefeed rack 9, to effect a rearward movement thereof against the pressureof the spring 13 to disengage the feed rack from the pinion and thusfree the carriage from control of the escapement mechanism. The carriagerelease device 1S is actuated in a manner which will hereinafter appear.

A column stop bar 21 extends substantially throughout the length of thecarriage and is supported thereby on arms 22 which project from thecarriage. The column stop bar is provided with teeth 23 on oppositesides thereof-for the reception of bifurcated sheet metal column stops2e in the interdental spaces between the teeth on the bar. It will beunderstood that adjacent interdental spaces are situated a letter spacedistance apart and that the column stops may therefore be adjusted todifferent letter space positions along the column stop bar throughoutthe length thereof. From an inspection of Fig. 1 it will be understoodthat the column stops 2-1 have contact portions which extend rearwardlyfrom the column stop bar at varying distances, so as to provide a seriesof graduated column stops, each having a contact portion in a path oftravel different from the others. The longest column stop 24 is situatedat the right and the shortest at the left of the series on the columnstop bar. In the present instance four column stops are shown.

A series of denominational stops 25 is arranged for movement fore andaft of the machine in openings in a guide plate 26 fixed to the topplate 4 of the machine. This guide plate is provided with slots oropenings 27, as shown in Fig. 11, to support the denominational stopsagainst lateral movement and to guide said stops in theirmovements foreand' aft of the machine. In the present instance each denominationalstop' constitutes a part of a variably movable actuating lever orfulcrumed member 28, the levers extending upwardly in the rearpart ofthe machine and being connected to key controlled actuating devices in amanner which will hereinafter appear. Each of the fulcrumed members orlevers 28 has a segmental slot 29 which extends longitudinally thereofintermediate the ends of the lever. lVhen the members 28 are in thenormal position all of the segmental slots 29 are in register and asingle fulcrum or pivot rod 30 extends through the slots 29. From anexamination of Fig. 4t it will be observed that spacing sleeves 31surround the fulcrum rod 30 and are arranged intermediate the levers 28in order to maintain them properly spaced apart on their pivot rod.

f The ends of the fulcrum rod 30 are secured by screws 82 to supportingarms 33, arranged outside of the series ot' levers ,2S and extendingfore and aft of the machine. These supporting arms 88 are pivotallysupported at their forward ends on a shaft 34k, which latter is fixed byscrews 35 in bearings in upwardly extending bracket arms 86. The arms 36are, or may be, formed as a part of a cross bar 37 fixed to the frame ofthe machine. From an inspection of Figs. 1 and 3 it will be observedthat a universal bar 38 has its bent ends riveted at 39 to the sidesupporting arms 3?) which support the fulcrum rod 30. The universal bar38, side arms 33 and the fulcrum rod 30 thus constitute a frame adaptedto swing around the shaft 34 as a center. This frame is connected to oneend of a contractile spring 33a, the other end of said spring beingconnected to one of the bracket Aarms 36 so as to exert a pull on theframe to return it to the normal position, shown in Fig. 1. The u'nderside of the universal bar 38 is provided with a example, at a, ZJ, c andCZ in Fig. 1, without l disturbing the levers 28 from their normalpositions. Obviously, however', each ofthe .levers 28 -is adapted toreceive a variable movement, depending von the position of the fulcrumrod 30 in the slots 29.

r[he key actuated means by which a vari'- able position of the fulcrumrod 80 is attained, in the present `instance, comprises a series of fourso-called. column selecting keys 4l, arranged in `rear of and above thedenominat-ional keys 42, and in the rear of the ordinary printing keysin the keyboard of the machine.. Each column selecting key is providedwith a stem 43 slotted to receive the forward end of a key actuatedlever 44, pivoted on a pivot rod 45,-fixed to the frame of the machine.From an inspection of Fig. 8 it will be observed that collars 46 aresecured by screws 47 to the pivot rod 45 outside o-f the right-hand andleft-hand key levers 44. `Intermediate spacing sleeves 48 are mounted onthe pivot rod 45 between the levers 44 to maintain them properly spacedand to prevent t-he movement of the levers along the'pivot rod 45. Eachof the levers 44 is, as will be seen, pivoted intermediate of its endsoas to constitute a lever of the' first order, the rear end of each ofthe first three of said levers, counting from right to left` having aninteriorly threaded bearing port-ion 49 forthe reception of a screw 50.Each screw constitutes an adjustable contact device for coperation withone. of the c0nv tact faces 40 on the universal bar 38. The

equal extent of key depression which is lim` ited by a contact face 51on each lever engaging the shaft 34, as shown in Fig. 6, therebyarresting the fulcrum carrying fra-me and fulcrum rod 30 in theirmovements to the shifted positions. The stepped faces 40 on theuniversal bar 38, however, afford varying extents of movement bydifferent column selecting keys 4l, through a differential or variablemovement of the frame and the fulcrum rod 30 which is carried.v thereby,as has been hereinbefore explained. Each key stem 43 of the columnselecting keys, is guided in openings in guide plates 52 and A coiledexpansion spring 54 surrounds each ke v stem, and bears at its lowerendagainst the guide plate and at its upper end against the associatedlever 44 to elevate the key and return the parts connected therewith tonorl'nal position. Each key stem is limited in its upward movement by anenlargement 43a at the lower end thereof engaging the guide plate 53.

Referring now to the mechanism by which the denominational stops areactuated, itV

openingsin the guide Vplates and 5?. Each key stem 55`is slotted toreceive the forwardly projecting` arm ot' an angular lever, indicated asa whnle by the reference numeral 56. From an inspection of Fig. 2 itwill be seen that earl-.i ot'V these levers comprises a forwardlyextending arm 57, carried by a yoke-like membe1 nhich extendstransversely of the machine and has rearwardly extending varms 59 whichare pivoted on a pivot rod 60, said rod being secured at its ends to theframe of the machine. These yoke-like members 58 are nested as shown,andare maintained. spaced of the'series of denominational keys whichrare connected to the yoke-like portions of the key levers. From aninspection of Figs. l and 2 it will be seen that adjacent to each of theinner arms 59 of the denominational key levers there is arranged anactuating lever or member64, provided with an offset laterallyextendingprojecticn or lug which extends beneath the inner arm 59 of theadjacent denominational key lever.

These Ylevers 64 are pivotedon the pivot rod 60 and each has a dependingarm which is connected at 66 to a rearwardly extending push link 67.Each link, at its rear end, extends through al guide opening ina guideplate 68, fixed to the frame of the machine. The yrea-r end of each link67 is pivoted at 69 to the lower end of an associated denominationalstop lever 28 and by which the lever is supported andV actuated. Acontractile spring 7 0 is connected at one end to the depending` arm ofa lever 64 and at its forward end to a plate 71 secured to theframe ofthe machine. Each lever 64`has an upwardly extending arm 72 for purposeswhich will hereinafter appear. It will be understood that the returningspring for each lever 64 is effective to return the associated keyactuated denominational lever 56 and its denominational key 42 to normalposition. The pull exerted by the spring is likewise effective to movethe link 67 forwardly and return the associated denominational stoplever 28 to its normal position around the fulcrum rod 30. The forwardmovement of the lower end of each stop lever 28 is limited by contactwith the guide plate 68, whereas a rearward movement of the lower end ofeach stop lever is -limited by a set screw 73, received in a tappedopening in the frame of the machine.

llSO

At the depression of a denominational key, movement is transmittedthrough the associated denominational lever 56. The movement of thelatter around the pivot 60 is effective to move the associate lever 64against the pull of the spring 70, and to actuate the correspondingdenominational stop lever 28. A turning movement of the latter aroundits pivot 30 is effective to move the corresponding denominational stopinto the path of one or another of the column stops, depending on theextent of movement of the lever 2S, and its extent of movement isdependent. as hereinbefore explained, upon the position of the pivot rodor fulcrum 30 for the levers 2S. The four positions of the pivot rod 30to vary the extent of pivotal movement of each of the levers 528 areshown at a, Z2, c and d in Fig. l. It will be understood therefore thatan actuation of a column selecting key 4l is first effected, in order todetermine the position of the fulcrum rod 30, and to determine withwhich of the column stops t-he denominational stops are to coperate; inshort, to select the column or columnar field where the carriage is tobe arrested by the cooperation of the different denominational stopstherewith. Thus, should the operator desire to arrest the carriage inthe second columnar field, it is merely necessary to depress the secondcolumn selecting key from the left, bearing the index numeral 2. Theeect of the depression of this key is to bring the contact device 50carried thereby into engagement with the corresponding contact face orstep 40 on the differential universal bar 38 and to swing the frame, ofwhich the said bar is a part, around the shaft 34 as a center. Thedepression of this column selecting key is effective to move the framewhen the pivot rod 30 will be positioned, as indicated at Z) in Fig. l.If, therefore, any denominational key be depressed while the fulcrum rod30 is in this position. then the corresponding denominational stop willbe projected into the path of the second of the column stops Q4,counting from left to right, to arrest the carriage within the secondcolumnar field and'at a denominational position within said fieldcorresponding to the particular denominational key depressed. It will beunderstood that each denominational stop will at this time be moved auniform distance and will be brought into the path of this same secondcolumn stop, as hereinbefore indicated.

I have found it desirable to provide locking means for locking thefulcrum rod 30 in any one of the three positions indicated at 5, c and(Z in Fig. 1 to which the fulcrum rod may be shifted, in order that theoperator after depressing a column selecting key may release it and befree to actuate the denominational stop at will and without thenecessity of maintaining pressure on the column selecting key untilafter the denominational key is actuated. To this end I have providedeach key lever 44 with an upwardly extending engaging member 74 havinginclined edges Or cams 7 5 and 76 on the front and rear sides thereof,respectively. The lower edge of each inclined edge terminates at alocking notch or slot 77. A universal locking device or bar 7 8 iscarried by arms 79 arranged on opposite sides -of the series of levers44. These arms are pivoted on the pivot rod 60 and are held againstmovement longitudinally thereof by collars 79a. The locking bar istherefore adapted to swing around said pivot rod 60 as a center fore andaft of the machine. This locking bar is adapted to coperate with theinclined edges 7 5 and the forward locking notches 77 of the engagingdevices. A second locking bar 80 is connected in a like manner to arms81 which are pivoted on the pivotrod or shaft 60. This locking bar 80 isadapted to cooperate with the inclined edges 76 and the rear set oflocking notches 77. A contractile spring 82 is connected at one end to apin 83 which extends upwardly from the locking bar 7 S, whereas theopposite end of y said spring is connected to a pin 84 which extendsupwardly from the locking bar 80. The spring therefore exerts a pull tocause the locking bar 78 to be held against the inclined faces 75 on themembers 74. It also tends to cause the two bars 7 S and S0 to be drawntoward each other, but the bars under certain conditions which willhereinafter appear are limited in their movements toward each other by aprojecting arm 85 which extends forwardly from one of the arms S1 forengagement with an arm 79 of the forward locking bar, as shown in Fig.l. The relative movement of the bars 7 8 and SO toward each other isthus limited. A contractile spring 86 is connected at one end to the pin84 and at its opposite end to the shaft 34. The pull of this spring isgreater than the pull of the spring 82, and vthe spring S6 tends tonormally maintain the parts in the position shown in Fig. l. If at thistime a column selecting key be depressed, as indicated in Fig. 6, therear end of the corresponding key lever will be elevated. The inclinededge or cam 75 will effect a forward movement of the locking bar 78 tomove it against the pull of its spring 82 until the forward lockingnotch 77 has been brought into register with the forward locking bar.The spring 82 is then effective to move the locking bar 78 into thenotch, to lock the rear end of the actuated lever 44 in its elevatedposition, thereby locking the associated contact device 50 in itsshifted position and maintaining the fulcrum 30 up in the position towhich it has been shifted on the depression of the column selecting key.The parts will remain in this position until a denominational key isdepressed to effect a forward movement of the denominational stop. Vhenthis is done the movement of the lever 56 is effective to produce a.movement of the corresponding lever G4, thereby moving the upper arm 72of this last mentioned lever forwardly to effect a forward movement ofthe locking bar 80 into the rear locking notch 77, as represented inFig. 5. As the locking bar 8O moves foru'iardly the contact arm 85 iseffective to force the locking bar 78 to the releasing position as shownin Fig. 5, thereby disengaging it from the locking projection 74. Thereis a slight drop between each engaging device 74 and the locking bar 80to assure proper engagement between these parts when a disengagement iseffected between a locking device and the locking bar 78. It will beseen that while the locking bar 78 vis disengaged from the key actuatedlever 44 it, nevertheless, is at this time maintained locked againstreturn movement by the locking bar 80. Vhen, however, the carriage hascompleted its travel and been arrested by a coperation of the previouslyselected column stop with the denominational stop controlled by theparticular key depressed by the operator, then the denominational keymay be released and as it returns to normal position the associatedshown in Fig. l, where it is again inposiarm 72 will move rearwardly.This movement of the arm 72 releases the locking bar `8O, and thereturning spring 86 moves the said locking bar out of the rear notch 77and out of engagement with the locking projection 74 on the previouslydepressed column selecting key 44. This key lever 44 may thereforereturn to normal position as tion to be actuated by the depression ofthe -appropriate column selecting key and to be automatically locked inits actuated position. During the return of the locking bar 78 to normalposition it is prevented from rengaging in the forward notch 77 of theactuated lever 44 by reason of the drop which has been effected-betweenthe engaging member 74 on the actuated lever and the locking bar 80, aspreviously described. From the foregoing it will be seen that at `thedepression of a'column selecting lief. t0 move the fulcrum totheappropriate position determined by the particularcolumn selecting keyactuated, the parts will be automatically locked in the actuatedposition. That is to say, the column selecting key will be locked in thedepressed position, the contact device will be locked in its actuatedposition up against the universal bar 38, and the frame carrying thefulcrum rod 3() will be locked against return movement under the pull ofthe spring 33a and in the positionto which it has been moved by thedepression .of the column selecting key. It will also be understood thatupon the first depression of a denominational key the locking mechanismwill be automatically released to afford a return movement of the partsto normal position.l

I have provided means whereby the release of the carriage to effect atabulating operation or movement does not take place until the columnselecting key has been depressed and locked in its operative position,and until a denominational key has been depressed. Vln order to provideagainst the release of the carriage until after a column selecting keyVhas been depressechl have provided means whereby the carriage releasemechanism is normally inoperative and cannot be released unless a columnselecting key has been actuated prior to the actuation of a columnselecting key. Thus each of the levers 64 is provided with a rearwarlyeXtending engaging Aprojection 87, which, in

the normal position of the parts shown mounted to swing fore and aft ofthe machine. Tlie rock shaft carries a rearwardly extending crank arm 91provided at its rear end with a stop 92 which engages a cross bar 93 ofa frame 94. The rear end yof the crank arm 91- has pivoted thereto at 95an upwardly` extending link 96 which in turn is pivoted at 97 to theinner ends of two toggle links 98. The rear end of the rear toggle linkis pivoted at 99 to a bracket 100, secured to the cross bar 15, whereasthel forward end of the forwardv toggle link is pivoted at 101. to thecarriage releasing device 18.

It will be understood thereforethat a rearward movement of the universalreleasing bar 88 is effective to turn the crank arm 91 upwardly, therebytransmitting movement through the links96 and 98 to the carriagereleasing device 18, which movement isy effective to shift the feed rack9 rearwardlyI out of engagement withv the coperative feed pinion 14. Ashereiiibefore stated, thev normal position ofthe parts is such, however,that the actuating projections 87 will not engage the releasing bar 88,.so that a depression of a denominational key, when the parts are inthev positions represented in Fig. l, would be ineffective to prod-nce atabulating movement of -the carriage, inasmuch .as the carriager releasemechanism could not be actuated. I have provided means, however,controlled by a depression of a column selecting key for elevating theuniversal bar 88 into the path of the enhereinbefore referred to,comprises parallel side arms which are pivoted at 102 to rearwardlyextending arms 103 on the bracket 3G. The frame therefore is mounted toturn on the pivots 102 as a center, in order that the forward end of theframe may be elevated from the position shown in Fig. 1 to thatindicated in Fig. 5, where the releasing bar is held in coperativerelation with the engaging projections 87, on the levers 64. The meansfor swinging the frame in the manner specified consists, in the presentinstance, of hook-like extensions 104 on the key levers 44. One of thesedepending hooklike engaging projections is provided on each lever 44,and they normally extend beneath the pivot rod 90. An upward move` mentof the rear end of any of the levers 44 is effective to bring about anengagement between the engaging hook 104 on the lever and the pivot rod90 to swing the frame 94 around its pivots 102, from the position shownin Fig. 1 to that indicated in Fig. 5. At this time, therefore, thereleasing bar and the carriage release mechanism controlled thereby areadapted to be actuated, to release the carriage from the control of theescapement mechanism to afford a free travel of the carriage until it isarrested by the cooperation of a column stop with the projecteddenominational stop. A contractile spring 105 is connected at one end toa pin 10G projecting from the crank arm 91. The opposite end of thisspring is connected to a pin 107 which extends from the fixed cross bar87. The power of this spring is exerted to pull the arm 91 down, therebymoving the releasing bar 88 forwardly to normal position. rlhis alsoeffects a down pull on the link 96 to tend to maintain the releasingdevice 18 in the position shown in Fig. 1. The sto-p 92 engages thecross bar 93, thus limiting the downward movement of the rear end of thecrank arm 91 and the parts controlled thereby. The power of the spring105, connected in the manner described, is likewise effective to movethe frame 94 downwardly at its forward end and maintain the universalbar out of cooperative relation with the projections 87. rlhe spring 105therefore acts for a two-fold purpose. Stops 108 are carried by the sidearms of the frame 94 and contact with the cross bar 37 to limit thedownward swinging movement of the frame 94 under the pull of itsreturning spring 105.

From the foregoing description it will be understood that in order toeect a tabulating movement of the carriage it is necessary to firstactuate an auxiliary or column selecting key in order to render the keycontrolled carriage releasing mechanism operative; that such depressionof a column se-'A lecting key is effective to determine the position ofthe fulcrum 30 for the denominational stop levers 28 that when thefulcrum is shifted it is automatically locked in its shifted position bythe engagement of the locking bar 78 with a projection 74 on theactuated column selecting lever 44; that a denominational key may now bedepressed and its depression is effective to give the requisite amountof throw of the corresponding denominational stop lever, to bring thecorresponding denominational stop into the path of the particular columnstop which has been selected, as determined by the operation of theparticular column selecting key actuated; that at or about the time thedenominational stop has been given the requisite amount of movement tointerposition it in the path of the proper column stop, a release of thecarriage will be effected to afford a movement of the carriage untilsuch time as the projected denominational stop and the selected columnstop are brought into cooperation to arrest the carriage; that whenpressure is released on the denominational key, the locking mechanismwill be automatically released to afford a return movement to normalposition of the column selecting key and the parts controlled thereby.It will also be understood that the variation in the position of thefulcrum rod 80 brings about and determines the variation in the extentof movement that may be transmitted to each of the denominational stops;that the means by which the fulcrum rod 30 is shifted relatively to thedenominational levers 28 constitutes leverage changing means by whichthe extent of movement of each denominational stop is controlled and thecolumnar position of arrest of the carriage is determined, and that thevariable movements of the denominational stops are toward and away fromthe column stops or in the direction in which the denominational stopsmove to bring them into cooperative relation with 1 the column stops.

It should be understood that when the part-s are in the normal positionthe fulcrum rod 30 is maintained in the lowermost position, as indicatedin full lines in Fig. 1, and that this position is one of the four whichdetermines the extent of movement to be transmitted to thedenominational stop levers. In other words, when the fulcrum 30 is inthe position indicated at a in Fig. 1, the denominational stop leverswill receive their greatest extent of throw in order to enable thedenominational stops to be interposed in the path of the shortest columnstops, or the first of the column stops, counting from left to right,and it is unnecessary to shift the fulcrum from this position. Theleft-hand column selecting lever bearing the index numeral 1 thereforeterminates before it reaches the universal bar 38, and has no contactdevice 50 like the other three column selecting key levers. It 'followsAthat when; this first column selecting key lever is depressed, nomovement- Will be transmitted to the fulcrum carrying frame, and thefulcrum will' remain in the position in'- dicated at a ine Fig. l.Inasmuch, hovvever, as the carriage release mechanism cannot be actuateduntil after the depression of a-column selecting key I have provided acolumn select-ing key bearing the index numeral l in order that this keymay be actuated to carry the releasing bar 8S up into position Where itmay be actuated by the engaging projections 87. In other words, While iti's unnecessary to actuate the first of the column selecting keys inorder to determine the position of the fulcrum 30, it is necessary toactuate said key in order to render the denominational stop lmechanismoperative to release the carriage.

From a considerationv of the foregoing description it will be seen thatif the operator desires to use the construction asa mere columnselecting mechanism, it is only necessary to depress the columnselecting key and then depress theE denominational key bearing the indexmark 'indicating the decimal point. The carriage will: be released onthe depression ofthis last mentioned key and Will be arrested after asingle travel at the desired columnar field. If, however', it is desiredto select a given denominational position, say, at ten thousandsposition Within, say, the second columnar field, `the column selectingkey bearing the index numeral 2 is first depressed and the ten thousandsdenominational key is then depressed, and the carriage Will after asingle run be arrested in the ten thousands position in thel secondcolumnar eld.

I believe that I am the first to devise the combination of cooperativetabulator stops and leverage changing means operable at Will to cause avariation in the extent of movement of certain of said stops relativelyto others to vary the point of arrest of the carriage, and Wish to beunderstood as claiming such subject-matter broadly.

Various changes may be made Without de'- parting from the spirit andscope of my invention.

What I claim as new and desire to secure by Letters Patent, is

1. In a typeivritingmachine, the combination of awcarriage; andtabulator mechanism for arresting the carriage at variable positions inthe travel thereof, said mechanism .including afulcrumed member movablevarying extents and by the variation in extent of movement of whichV avariation in position of arrest ofL the carriage is determined, andmeans for varying the position of the fulcrum of said member and therebycause a variation in thev extent of movement Which may be given said'member.
